Toall whom it may concern:

Be it known that we, CHARLES E. WAREAM and CHARLES L. BRALEY, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certa'innew and useful Improvements in Pressure Attachments for Garment-Presses, of which the following is a specification. This invention relates to garment presses 2nd particularly to power attachments there- More specifically the invention relates to a garment press provided with manually operable means for closing it and power mechanism preferably of the neumatic type for exerting affinal increase pressure upon the pressing members for performing the final pressing operation.

The invention may be; further briefly summarized as consistin in the construction and combination 0 parts hereinafter {set forth in the following description, drawand claims. "side elevation of a machin i file n "Referring to the drawings ure 1 is a pressure mechanism applied thereto; Fig. 2 1s a View showing the Valve mechanism with the exhaust valve shown in section on the line'2 in Fig. 3; Fig. 3 is a sectional .view on the line 3-3 of Fig. 2; Fig. 4 is an enlarged View of a portion of the machine with the parts in the positions they assume 2 when the press is closed; Fig. 5'is a front .5 view of the lower treadle with the parts in 'thei same position shown in Fig. 4; Fig. 6 is a horizontal sectional view on the l1ne 6 -6 of Fig. 4; Fig. 7 is a top plan of the final pressure mechanism removed from the machine, and Fig. 8 is a perspective. view of the pressure head.

In the arran ement shown in the drawf ings the main rame comprises ,a base 1, a forwardly extending buck support 2 and an upwardly extending press head supporting.

bracket 3. The main frame also has a-rearwardly extending treadle pivot bracket, 4.

' Pivotally mounted on a pin 5 arranged in the treadle bracket 4 is the main treadle 6 which extends out to the front of the ma-- chine and is there provided with an enlarged foot portion 7 arranged conveniently for the operator.

The treadle 6 is provided within the frame with a roller 8, shown in dotted lines, for engaging an arm 9- of a lever pivoted at 10 in the frame and having an upwardly exweight 17 A spring 18 is arranged between the rear end of the lever 14 and the base and tends to open the press. A spring 19 is arranged between the base and the arm 9. Many of-the. parts ,just described are shown in dotted lines but this mechanism forms no part of the invention except as it may enter into the combination so that a further showing or further description is not necessary.

Mounted on the buck support 2 is a buck or board 20 of any preferred type capable of cooperation with the head 16. i The foregoing mechanismv is substantially the same as that disclosed in the application of CharlesL. Braley filed Aug. 14, 1916, Serial Number 114,7 94 and such mechanism only forms a part of this invention 'in sofar as it enters the combination .as .before stated.

The feature whichforms the specific subj'ect matter of this application is the power mechanism. a p

This power mechanism comprises a frame 21, Fig. 7, adapted to be applied to the buck support 2 and supporting a power cylinder 22. Within the cylinder 22 is a piston 23 secured to a piston rod 24 extending down-- ward and provided with a pressure head comprising a sleeve 25 and a plate portion,

25 horizontally disposed and adapted for engagement with the flat edges 26 of the main treadle which is preferably provided with spaced side portions for the purpose, as shown in Fig. 5. Thesleeve 25 is provided with opposed slots eachconsisting of a straight portion 27 and an abrupt in- I clined portion 28 communicating with the straight portion. These slots receive rollers 29 mounted onpins 30 secured in two downwardly extending arms 31 projecting from the lower head of the cylinder.

When the piston is in its upper ositon the rollers are at the lower ends of t e slots fluid pressure.

28, and the longer dimension of the plate I 25 is parallel with the length of the treadle 6. Therefore, the treadle can rise past the plate 25' to the position shown in Fig. 1. When-the treadle is down and the piston is moved down the effect of the rollers upon the cam slots 28, 27 is to turn the plate 25' until its longer dimension is, cross-wise of the treadle, in which position the ends of said plate lie'above the fiat edges 26 of the treadle, and in which position pressure of the piston is transmitted to the treadle and therefore applied to the pressing members and the work therebetween.

In order to control the motor means above described and to time it properly with the treadle a suitable valve and operating mechanism therefor is provided consisting of a casing 32 properly supported and in which is a supply chamber 33, Fig. 3, communicating with a supply 34 of air or other This chamber communicates by a port 35 with a chamber 36, said port'being controlled by a hand operated valve 37 provided with a stem 38 having a threaded portion 39 engaging a threaded portion of the casing. The stem 38 passes through a stufiing box structure 40 which prevents leaka'ge at this point. This valve is used to regulate the flow of air or other liquid to the cylinder as will appear. Below the chamber 36 the casing 32 is provided with a combined inlet and exhaust. chamber 41 which communicates by means of a pipe 42, with the upper end of the cylinder 22 whereby any air or other liquid supplied to the chamber 41 will pass directly to the cylinder and move the piston therein downward. The passage of air or other liquid from the chamber 36 to the chamber 41 is controllediby an inlet Valve 42 swiveled, as willappear, upon the end of a stem 43 passing through a stuffing box structure 44 to the outside of the casing 32. A spring 45 surrounds the stem within the casing 32 and tends to seat the valve. The chamber 41 communicates with an exhaust opening 46 controlledby a valve 47 having a gasket 48 and a recess 49 for receiving a head 50 which is held loosely in the recess by a ring 51 threaded or otherwise secured. in the valve. The head 50 forms a part 'of a valve stem 52 which extends out of the casing 32 through a stuffing box structure 53. The val e is held sealed by a spring 54 surrounding the stem 52. The outer end of the stem 52 is threaded into a clevis 55 pivotally connected to a rocker lever 56 which is secured intermediate its ends upon the shaft 57 mounted in the frame audits opposite end is pivotally mounted in a clevis 58 threaded onto the end of the valve stem 43 of the supply or inlet valve'already described. The shaft 57 also carries an operating lever 59 having one of its two arms pivotally c01 1- nected to a. main treadle operating rod 60 passing through the eye in an car 61 forming a part of the main treadle. ear the rod 60 is provided with a spring 62 Below this Assuming that the parts are in the position shown in Fig. 1 and that a garment has been placed upon the buck or board 20, the

operator depresses the main treadle 7 causing this treadle through the mechanism already described, to move the head 16 down upon the work. In performing this operation, however, the ear 61 engages the spring 62 and exerts sufficient pressure against this spring so that it shifts the valves in a position to close the exhaust valve and open the inlet with the result that fluid pressure is admitted to the cylinder above the piston therein causing the piston to move downward.- The downward movement of the piston causes the head on the end of the piston carrying the plate 25 to be cammed around in a position for the plate to bridge the two edges-26 of the main treadle and to engage these edges and exert a final pressure through the treadle mechanism upon the head. When the parts remain inthis" of the valves in a manner to close the inlet and open the exhaust, whereupon thespring 18 opens the press and the spring 23 moves the piston upward in the cylinder to normal or rest positlon causing the head at the end of the piston-to move the plate out of engagement with the treadle mechanism by the camming action of the walls of the slots in the head.
